Trouble setting up Java classpath

Saw an error while setting up an application called i2phex:
Code:
# ./run.sh
java.lang.RuntimeException: Failed to initialize phex.net.repres.i2p.I2PPresentationManager
        at phex.common.ManagerController.initializeManagers(ManagerController.java:78)
        at phex.Main.main(Main.java:161)

After seeing that I figured it was that I didn't have my classpath set up for java. I've set up classpath's before, but I don't know the directory to link it to. I know java is installed because this works:
Code:
# java -version
java version "1.6.0_10"
Java(TM) SE Runtime Environment (build 1.6.0_10-b33)
Java HotSpot(TM) Server VM (build 11.0-b15, mixed mode)

But I checked and don't see a classpath for it:
Code:
# echo $JAVA

I also checked "env" and there's no environment variable for it there. Searched for the needed directory in many places sites off Google suggested for a java classpath but I didn't have any of them. Many searches with "find / -name" and came up empty.

PS.- I'm using Backtrack 4 r2 if that helps. (This is Ubuntu Intrepid... old, I know)

JH_MANIFEST(1)							    Javahelper							    JH_MANIFEST(1)

NAME
jh_manifest - Adds or/and modifies manifests for jars SYNOPSIS
jh_manifest [debhelperoptions] [options] jar1 ... jarN jh_manifest [debhelperoptions] [options] DESCRIPTION
Javahelper tool to add or update manifests in a jar file. It can be used in two modes. If passed jar files, it will only process these jar files. Otherwise it will update all jar files in the packages it acts on. When processing a package, the debhelper(7) exclude option will make jh_manifest ignore matching jar files. FILES
debian/package.manifest (or debian/manifest) This file consist of a list of jar files and values to add to their manifests. Values in this file will take precedence over values in the original manifest (and command line arguments over values in this file). It is allowed to list a link in this file instead of an actual jar file, provided that the link can be resolved when jh_manifest processes it. If a jar file is listed here cannot be found, jh_manifest will print a warning, unless the jar file has been excluded. As of javahelper >= 0.32, you may add comments in this file. If the line starts with a "#" it is completely ignored. This file is ignored if jh_manifest is passed jar files via command line. OPTIONS
-c classpath, --classpath=classpath Sets the Class-Path attribute of all processed jar files to classpath. If not passed, then the CLASSPATH environment variable will be used in the given jar file do not have a Class-Path attribute. -m class, --main=class Sets the Main-Class attribute to class in all processed jar files. -o options, --javaopts=options Sets the Debian-Java-Parameters to options in all processed jar files. This attribute is used by jarwrapper to start java with extra options (e.g. to make more memory available). -j /path/to/java/home, --java-home=/path/to/java/home Sets the Debian-Java-Home attribute to /path/to/java/home in all processed jars. This attribute is used by jarwrapper to determine which JVM to use. EXAMPLES
An example debian/manifest file: # use the symlink so we do not have to update with the next upstream release. usr/share/java/my.jar: Class-Path: dep1.jar dep2.jar Main-Class: some.awesome.Class usr/share/java/dep2.jar: Class-Path: dep1.jar SEE ALSO
debhelper(7) This program is a part of javahelper and uses debhelper as backend. There are also tutorials in /usr/share/doc/javahelper. AUTHOR
